If you removed all three stretch release adhesive strips, congratulations—you can now remove the battery! If not, follow the next two steps to separate the adhesive with isopropyl alcohol and a plastic card.

If the top strip remains, prop up the top edge of the phone.

If either of the bottom strips remain, prop up the left edge of the phone (the side with the volume buttons).

Use a pipette or syringe to apply a few drops of highly-concentrated isopropyl alcohol (over 90%) to the elevated edge of the battery.

Wait one minute for the isopropyl alcohol to flow under the battery and soften the adhesive.
